Preface
In Vue, there are three types of modules that request back-end interfaces:
- view-resource
- axios
- fetch
Here we use axios to request the back-end interface.
installation
Enter the directory of the vue project and execute:
npm install axios --save
use
The http request methods supported by axios are as follows
- axios.request(config)
- axios.get(url[, config])
- axios.delete(url[, config])
- axios.head(url[, config])
- axios.options(url[, config])
- axios.post(url[, data[, config]])
- axios.put(url[, data[, config]])
- axios.patch(url[, data[, config]])
This article does not focus on the use of axios. Here we take get as an example. When using the axios receiving interface to return, you need to use the arrow => symbol to get the correct this pointer.
this.$axios
.get("/userInfo")
.then(
(response) =>
// handle success (this.userdata = response.data) )
.catch(function (error) { // handle error console.log(error);
})
.then(function () { // always executed
});
If you don't want to use an arrow function, you can use a variable to get the this pointer externally, but it is recommended to use the above writing.
.$axios
.get("/userInfo")
.then(
function(response){
)
.( (error) { console.log(error);
})
.then( () {
});
